Thanks to all who have weighed in on my situation. My wife and I have come to a decision after many consultations with my local urologists/RO and hematologist, as well as my PCP. For an array of reasons--no clear lesions on 2 MRIs, no metastases on PSMA-PET, low PSA density (.04-.06), large prostate (114 cc), age 80, "normal" PSA (5.1, 7.6, 4.5) in recent months, Artera and Decipher not alarming, BPH not causing unacceptable symptoms--I will have PSAs in August and December and an MRI in early 2027 with a possible PET scan following the MRI. We'll see what happens with this approach and adjust if/when we need to do so. I'm still entertaining the possibility of some form of ablation to reduce the size of my prostate so that if/when I decide on treatment, radiation options are included (prostate too large for radiation or focal therapies at this time). And who knows, maybe another treatment that matches my PCa and profile will emerge in the meantime!
